The second mining section of No.2 mining area of Yangquan No.4 coal mine is now under the 8233 coal seam of the Lower Carboniferous Taiyuan Group with 8243 lower stratified face. The longwall inclined stratified mining method is adopted. The working face length is 178m and the strike length is 1076m. Coal Thick 5.43 ~ 7.11 meters, the average thickness of 6.18 meters. Two layers of mining, the stratification for the general machine mining, manual laying of double metal mesh roof, with an average mining height of 2.0 meters; the next stratified for the fully mechanized mining, the use of West German WS1.7 ~ 2 / 3.5 type shield bracket, France SIRUS-400 type
